A Tour of the Labor Market
The noninstitutional civilian population is the number of people potentially available for civilian employment.
The civilian labor force is the sum of those either working or looking for work.
Those who are neither working nor looking for work are out of the labor force.
The participation rate is the ratio of the labor force to the noninstitutional civilian population.
The unemployment rate is the ratio of the unemployed to the labor force.

The Large Flows of Workers
On the extremes, the unemployment rate may reflect two very different realities:– An active labor market, with many separations and many
hires (very short duration of unemployment)– A sclerotic labor market, with few separations, few hires,
and a stagnant unemployment pool (long expected duration of unemployment)

Movements inUnemployment
Fluctuations in the aggregate unemployment rate affect:– The welfare of the unemployed– Wages of those employed– Higher layoffs = higher risk of losing their Higher layoffs = higher risk of losing their

Other Labor Market Issues
How many employed are working part-time only? How many of those want to work full time?
How many are employed as temporary workers (temps)?
Do temps (and others) have any job security? Do they want job security?
Nominal vs. real wages. Other benefits.

Wages
Real wages in different countries are….different.
Wage Determination
Common forces at work in the Common forces at work in the determination of wages (within a determination of wages (within a specific labor market) include:specific labor market) include: A tendency for the wage to exceed the A tendency for the wage to exceed the

Dependency of wages on labor-market Dependency of wages on labor-market and firm-specific conditions.and firm-specific conditions.
Individual Bargaining
How much bargaining power a worker has depends on:1. How costly it would be for the firm to replace
him—the nature of the job.
2. How hard it would be for him to find another job—labor market conditions.
Efficiency Wages
Efficiency wage theories - link the productivity or the efficiency of workers to the wage they are paid.
These theories also suggest that wages depend on both the nature of the job and on labor-market conditions.
Wages, Prices, and Unemployment
The aggregate nominal wage, W, depends on three factors:
1. The expected price level, Pe
2. The unemployment rate, u
3. A catchall variable, z, that catches all other variables that may affect the worker’s bargaining position (labor market conditions).
W P F u ze ( , )( , )
Wages, Prices, and Unemployment
1. Both workers and firms care about real wages (W/P), not nominal wages (W).
2. Higher unemployment weakens workers’ bargaining power.
3. Safety nets:1. Unemployment insurance
2. Minimum wages
3. Employment protection
Price Determination
The production function is the relation between the inputs used in production and the quantity of output produced.
Assuming that firms produce goods using only labor, the simplest production function can be written as:
Y A NYY = output = outputNN = employment = employmentAA = = labor productivity,labor productivity, or output per worker or output per worker
Price Determination
Firms set their price according to:
P W ( )1 The term The term is the is the markupmarkup of the price over the of the price over the cost of production. If all markets were perfectly cost of production. If all markets were perfectly competitive, competitive, = 0, and = 0, and PP = = WW..
The Natural Rate of Unemployment
This section looks at the implications of wage and price determination for unemployment.
We assume that Pe = P, and that nominal wages depends on the actual price level, P, rather than on the expected price level, Pe.
Wage setting and price setting determine the equilibrium rate of unemployment.
The Wage-Setting Relation
Earlier, we stated that the nominal wage rate was determined as follows:

Equilibrium Real Wages and Unemployment
An increase in unemployment benefits leads to an increase in the natural rate of unemployment.
Equilibrium Real Wagesand Unemployment
An increase in markups decreases the real wage, and leads to an increase in the natural rate of unemployment.
